A new study, by Levente Orbán and Catherine Plowright from the University of Ottawa in Canada, shows that the markings at the center of a flower are not as important as the markings that will direct the bees to the center. The work is published online in Springer's journal, Naturwissenschaften - The Science of Nature.http://phys.org/news290951661.html

Evaluating stink bug responses to different visual stimuli may help manufacturers design better traps for monitoring the bugs.http://phys.org/news277731629.html
BiologyFri, 18 Jan 2013 11:40:39 EDTnews277731629Study may explain why wolves are forever wild, but dogs can be tamedDogs and wolves are genetically so similar, it's been difficult for biologists to understand why wolves remain fiercely wild, while dogs can gladly become "man's best friend." Now, doctoral research by evolutionary biologist Kathryn Lord at the University of Massachusetts Amherst suggests the different behaviors are related to the animals' earliest sensory experiences and the critical period of socialization. Details appear in the current issue of Ethology.http://phys.org/news277658504.html

BiologyWed, 13 Jun 2012 10:28:22 EDTnews258802089Growing brain is particularly flexibleScience has long puzzled over why a baby's brain is particularly flexible and why it easily changes. Is it because babies have to learn a lot? A group of researchers from the Bernstein Network Computational Neuroscience, the Max Planck Institute for Dynamics and Self-Organization in Gottingen, the Schiller University in Jena and Princeton University have now put forward a new explanation: Maybe it is because the brain still has to grow.http://phys.org/news196431902.html
Medicine & HealthTue, 22 Jun 2010 13:25:38 EDTnews196431902Human working memory is based on dynamic interaction networks in the brainA research project of the Neuroscience Center of the University of Helsinki sheds light on the neuronal mechanisms sustaining memory traces of visual stimuli in the human brain. The results show that the maintenance of working memory is associated with synchronisation of neurons, which facilitates communication between different parts of the brain. On the basis of interaction between the brain areas, it was even possible to predict the subject's individual working memory capacity. The results were published last week in the online version of the renowned journal PNAS.http://phys.org/news190373523.html
Medicine & HealthTue, 13 Apr 2010 10:50:01 EDTnews190373523Remembering the future: Our brain saves energy by predicting what it will see(PhysOrg.com) -- Researchers have discovered that the brain saves energy by predicting what it is likely to see. According to scientists in the Department of Psychology at the University of Glasgow in collaboration with the Max-Planck Institute for Brain Research, Frankfurt, Germany, the visual cortex does not simply react to visual stimuli but proactively predicts what it is likely to see in any given context - for example, within familiar environments such as your house or office.http://phys.org/news188638202.html

The study, published by Cell Press in the February 11 issue of the journal Neuron, uncovers a previously unknown developmental delay in a critical brain circuit that processes sensory information in a mouse model of fragile X syndrome.http://phys.org/news185027732.html

They show that learning from experience actually changes the circuitry in our brains so that we can quickly categorise what we are seeing and make a decision or carry out appropriate actions. The research is published today (13 May) in Neuron.http://phys.org/news161439430.html

This is what has been shown by the team of &Eacute;douard Gentaz, CNRS researcher at the Laboratoire de Psychologie et Neurocognition in Grenoble (France). These results, published March 16th in the journal PloS One, should improve learning methods, both for children learning to read and adults learning foreign languages.http://phys.org/news156697376.html
